To all whom t may concern.' y

Be it known that I, MORTIMER R. ANsTIoE, a citizen of the United. States, residing at Rochester, in the county of Monroe and State of NewYork, have invented certain The primary object of my invention is to" secure a thorough vaporization of the gasofv lene drawn from thejet or outlet opening in the mixing chamber by forcibly and violently throwing the against the wallsof the mixing chamber, and thus thoroughly breaking up all of the gasolene particles and causing their thor-l ough lvaporizationV and thorough mixture with the air, and as a consequence, practically a perfect gasolene mixture'is obtained, when it enters the engine cylinders.

In carbureters where the gasolene particles are drawn through the mixing chamber in a direction 'longitudinally of the walls of the mixing chambers, there remain in the mixture shall particles of gasolene some what in the nat-ure of a spray, and these are drawn into the engine cylinder and to that extent a thorough vaporization is ,not ob# tainedand a .perfect mixture is not obtained with a consequent deterioration in thel workingeiliciency of the'mixture when ignited.

In carrying out my present improvement, I provide means for imparting tothe incoming air a strong or violent whirling motion within the mixing chamber as it passesiilthe gasolene jet or Outlet opening,-whereby the gasolene particles which are sucked or drawn from the said jet or outlet openin are'thrown in Vviolent contact with the waV of the Amixing chamber and thoroughly lill broken up which will cause a more thorough vaporization of the gasolene particles.

Another feature of my present improvement is to provide means in the manifold between the jet or gasolene outlet and the intake valve of the motor for imparting to the mixture a violent whirling motion which also violently throws against 4the walls of the manifold any particles of gasolene which were not broken or dissipated in the mixing chamber, thus continuing this whirlparticles of gasolenel Iing motion suciently to accomplish a thor- Patenten sept. io, 1912.

cessively whirling the mixture in opposite,

U Another feature of the present invention- ,.ls to subgect the mixture when it leaves the directions as it passes through the manifold,

which reverses the whirling direction of the mixture several tim s as'it passes through the manifold. l This invention is capable of'us'e with either a single jet carbureter, or with a plurality"- jet carbureter.

In the accompanying drawingwFigure l is a sectional view showing my invention applied to a single jet .carbureten Fig. 2 is a sectional --view of a plurality jet carbureter with my improvement applied thereto, the section being shown longitudinally throughl the float chamber and one of the gasolene jet or outlet' conduits. sectional view of Fig. 2 taken at right angles to Fig.4 2. Fig. fl is av horizontal sectional view on the line 4 4 of Fig. 2.v Fig. 5 is a horizontal sectional view on the line 5-5 of Fig. 2. l

My present invention'may be carried out or used in' connection with any form of carbureter, in which the gasolene is drawn into the mixing chamber through an outlet. I have here shown it in connection with the ordinary jet type of carbureter'and with the ordinary typeof float chamber for maintaining the gasolene at' a predetermined level in the jet conduit or outlet opening.v

Referring now to the drawings, l ndicates thev ordinary form of float chamber in which is located a iioat 2, pivoted at Vthe point 3 and operating a valve 4, which controls the asolene inlet 5. from a source of supply. full detail description of this construction is well-known and' understood to those skilled in this art and it is sufficient to say that when the gasolene reaches the predetermined `levelin the chamber 1,

Figi 3 is a .the iioat lifts and the valve 4 is closing the inlet opening 5. When thelevel.

is lowered'the iioat-2 falls with it-valid'lifts the valve 4 from its seat permitting-the gas-` olene to ilow'in the chamber 1 until the prei.' determined level .is again reached, when the.;`

` a single jet carbureter in which 6 is the inlet ave shown'onl two branches 8 and 9 in the manifold, desire it understood that the number of branches may Vvary according to the conditionto be met. For the pur-v pose of simplicity and illustration and description,^I here show two branches forthe manifold. Located 4in the part 7 ofthe manifold 'is-a 'throttle 10 of any desired form, the operation of whichis understood by those skilled in the art and a-description isunnecessary. In the single jet type of carbureter, it is usual to provide an auxiliary 'air-passage communicating with the mixing chamber. The auxiliary air-passage or opening -is of the form shown at11, and it is provided with the well-known Spring actuated -valve 12, for controlling the air-opening or inlet to the passage 11. This forms no part of the present invention and is also well understood. One part of my improvements consists in Vproviding means in the air-passage 6, fory imparting to the incoming air a violent whirling motioxi'be- .fore it reaches Vthe gasolene ]et' or outlet opening, which communicates with the mixlmg chamber 15.-

here shown, the means of'iniparting the whirling motion consists in providing'a helicoidal wall 16 in the pas- 'i .sage 6, which provides a helicoidal channel 7. "Thislielicoidal channel will be of the .proper area in proportion to the requirements of the carbureter and' the en e with which it is used.. This helicoida channel impartsto theincoming air a violent whirlol'itleifopen j gasolene wliili ing' inthe form o ing motion as it passes the gasolene' jet or 14, and as a consequence Vthe is passing from the .jet-openough-.vaporization of'tli'egasolene and, as`

laconsequence,closer approaches the pro-' duction'of aperfect mixtureto he receivedY art of my Y.;

further whirling motion imparted thereto. However I 'my im rove- -inent further -proyide means iii the manifold for w 'motion to' "the: mixture'to continue the-vio ent throw- .il n' ofY any remainii pa'cles 'of gasolene 'ligillsithe wall'oft e'fmanifold, anld-thus Fig". l shewsiny invention as applied to -pipe, 7', 8A and 9 the manifoid. whiiei a very iine sprayhasits vparticles violently thrown against the wall .of the mixing chamber which breaks-'up .the -gasolene particles and causes a more thorpasses therethrough. The throttle 1Q interrupts the whirling motion of the passing mixture very materially and Will cause it to ass from the mixing chamber to the stem Ii -Byt reason of this, the direction of `'the helicoid 17 as compared tothe direction of the helicoid 16 is not very material.- My improvement .is carried thser .by'pi'oviding .in lthe .branches'o trhe. manifoldv ing motion or the ur' oses already 'described. Preferably t e ranches 8 and 9 are provided with means 'for successivelyv -reversing the helicoidal direction of the passing mixture. A`s` here shown, this means for-reversing thel whirling direction of the impart to thepassing mixture whirling motions in successive reverse directions.

By reason of the construction hereinbefore 'described, I am enabled to accomplish a thorough dispersion and breaking up of in the mixture and to accomplish a thorough vaporizationthereof with a perfect mixture lient increase ineiiiciency when ignited in t e engine cylinders.

In Figs. 2, 3, 4 and 5, I' show my invention applied to multiple jet carbureters. In this' provided, and these are Mseparately connected duits 2 7. There is a se arate air inlet 28 for each of these jet. ori ces,.and enich` inlet 28 is provided with a helicoidal channel 29 similar to that shown in Fig.-1. All'three of thesefinlet assages 28 communicate at 'their outlet Aen 30.and are common to the inlet" end 31 o fthe manifold 32. The manilfold in this instance, maybe provided with helicoidal walls andchannels like thatshown in Fig. 1,-"and the branch-'pv "hown) ofA the manifold. also be prousejd'iii-l communication with a multiple c l- 'inde' engine` The operation of this in tiple Yjet carbureter is identicall thesame as the-operation of the single car uretei so; far as. the action on the-particles 'of gasoleneis concerned. A throttlev 33 -is provided1 for carbureters: There is o'f vwhiclii'the flowv af gasolene therethrough is controlled-lin the 'usual manner.

nfeans' for im arting't'tlie Iiiixture a whirlallof the particles of the gasolene contained mixture consists of helicoidal walls 19, 20, 21, 22, 23 `and 24. These helicoidal walls entering the engine-cylinder with a'. conseinstance, three gasolene jet openings 26 are with theiioat chamber 1n by means of coniio 'vided with the helicoidal channels like-that, u shown in Fig. 1,-. where' the carbureter is N ii's assagesinot ias the mixing-'chamber'34 of each of the let iovidedA a. n e Y valve 35 for each of the let orifices bymeans- Having thus described my invention, what I claim and desire to secure by Letters Patent is:
